Radial artery occlusion in a 74-year-old diabetic woman with occlusion of bilateral internal carotid arteries and the left vertebral artery. a: DSA of the right forearm. b: DSA of the left forearm. Radial artery puncture was carried out successfully, but resistance was felt on inserting the guide wire near the puncture site in each side. Contrast was injected from the needles used to puncture each radial artery. The radial arteries on both sides are occluded, and the anterior interosseous artery, which had developed into a broad vessel via anastomoses, is contrasted. TRA was abandoned.
